Description

Technical Field

[0001] This application relates to the field of automated warehouse door opening technology, and in particular to an opening device for an automated concrete sleeper curing warehouse. Background Technology

[0002] Automated warehouses typically have multiple aisles and are mainly used for the curing of products that require insulation, such as automated concrete sleeper curing warehouses used for the insulation curing of precast concrete components. Precast concrete components are widely used in construction, transportation, water conservancy and other fields. Currently, most precast concrete components are produced through specialized production lines. Curing is one of the most important processes in the production of precast concrete components. Stacker cranes usually transport the precast concrete components to be cured from the production line into the curing warehouse for curing.

[0003] In existing technologies, a door opening mechanism is typically installed on the door of the maintenance warehouse for opening and closing the door. However, for the doors of a three-dimensional concrete sleeper maintenance warehouse, since each floor of the maintenance warehouse has a door, a complete door opening mechanism needs to be installed on each floor's door to control the opening and closing of the corresponding door, which increases the construction and maintenance costs of the maintenance warehouse. Summary of the Invention

[0004] This application provides an opening device for a three-dimensional concrete sleeper curing warehouse, which solves the problem that when the existing opening mechanism is used in a three-dimensional concrete sleeper curing warehouse, a complete opening mechanism needs to be installed on the warehouse door of each floor, which increases the construction and maintenance costs of the curing warehouse.

[0005] This application provides a door opening device for a three-dimensional concrete sleeper curing warehouse. The door opening device is installed on a hoist, and the hoist is used to move the door opening device to the front of the target warehouse door to perform the action of opening and closing the warehouse door.

[0006] The door opening device includes:

[0007] A door opening component, which is matched with a pre-set functional part on the warehouse door;

[0008] The lifting mechanism is used to drive the door opening component to move vertically, thereby driving the corresponding compartment door to move vertically through the cooperation of the door opening component and the actuating part, realizing the opening and closing operation of the compartment door.

[0009] The technical solution provided in this application uses a hoist to move the door opening device to the door of the maintenance warehouse that needs to be opened. The hoisting mechanism drives the door opening component to lift, which in turn drives the door to lift, thus realizing the opening operation of the designated door. After the picking / unloading operation is completed, the hoisting mechanism drives the door opening component to lower, thus completing the closing operation of the designated door. The operation is convenient and there is no need to install a door opening device in front of every door of the maintenance warehouse, which greatly reduces the construction and maintenance costs of the maintenance warehouse.

[0010] In some embodiments, the door opening component is a door opening hook, and the actuating part is a protrusion or recess that matches the door opening hook. By cooperating with the protrusion or recess in front of the door, the door can be lifted, and the lifting mechanism can be used to realize the lifting and lowering closing actions of the door. The structure is simple and the operation is convenient.

[0011] In some embodiments, the lifting mechanism includes a driving component and a vertically arranged linear groove rail. A lifting rod is slidably connected to the linear groove rail, and the bottom end of the lifting rod is connected to the door opening component. The driving component is used to drive the lifting rod to move vertically on the linear groove rail, thereby causing the door opening component to rise or fall and perform the action of opening and closing the compartment door.

[0012] In some embodiments, the inner wall of the linear guide rail is provided with a linear guide groove, and the outside of the lifting rod is provided with a first guide wheel that matches the linear guide groove. By providing a linear guide groove inside the linear guide rail and a first guide wheel outside the lifting rod, the sliding fit between the lifting rod and the linear guide rail is converted into a rolling fit between the first guide wheel and the linear guide groove through the cooperation between the first guide wheel and the linear guide groove. This reduces the friction between the lifting rod and the linear guide rail, making the movement of the lifting rod on the linear guide rail smoother.

[0013] In some embodiments, a guide sleeve is fitted around the lifting rod, the lifting rod is rotatably connected to the guide sleeve, the first guide wheel is mounted on the outside of the guide sleeve, and the driving component is connected to the guide sleeve to drive the guide sleeve to move vertically on the linear groove track.

[0014] The lifting rod is provided with a second guide wheel that matches the linear guide groove. The bottom of the linear guide groove is connected to an arc-shaped guide that is coaxial with the lifting rod. The arc-shaped guide and the second guide wheel cooperate with each other to make the lifting rod rotate in the guide sleeve, thereby driving the door opening component to rotate in the horizontal direction and cooperate with the action part on the door.

[0015] This application involves installing a guide sleeve on the outside of the lifting rod to rotate with the lifting rod, setting a second guide wheel on the outside of the lifting rod, and connecting an arc-shaped guide to the bottom of the linear groove rail. This allows the lifting rod to simultaneously rise and rotate as the second guide wheel rolls within the arc-shaped guide, thereby driving the door opening component to rotate and cooperate with the action part on the door to lift the door.

[0016] In some embodiments, the inner wall of the arc-shaped guide member is provided with a curved guide groove that matches the second guide wheel. The curved guide groove is smoothly connected to the straight guide groove and extends along both the axial and circumferential directions of the arc-shaped guide member. The second guide wheel moves in a spiral upward or downward motion within the curved guide groove, driving the lifting rod to rotate upward or downward. By providing a curved guide groove that smoothly connects to the straight guide groove within the arc-shaped guide member, the second guide wheel can smoothly transition into the straight guide groove when it moves in a spiral upward motion within the curved guide groove, thus improving the smoothness of opening and closing the door.

[0017] In some embodiments, the driving component includes a drive motor and a chain drive assembly installed inside the linear groove. The chain drive assembly is connected to the lifting rod. The drive motor drives the chain drive assembly to run, causing the lifting rod to move linearly in the vertical direction. The chain drive assembly can convert the rotational motion output by the drive motor into linear motion, thereby causing the lifting rod to move linearly in the vertical direction, realizing the opening and closing of the compartment door.

[0018] In some embodiments, two linear groove rails are provided, arranged in parallel, and connected by a crossbeam; the driving component is installed between the two linear groove rails to drive two lifting rods to move synchronously in the vertical direction on their respective linear groove rails; by providing two linear groove rails, it can be applied to wider storage doors. When the storage door is wide, actuating parts can be provided at the left and right ends of the storage door, and the two opening parts cooperate with the left and right actuating parts respectively to realize the opening of the storage door, thereby improving the stability of the opening device structure.

[0019] In some embodiments, the door opening device further includes an open position sensor and a close position sensor. The open position sensor, the close position sensor, and the lifting mechanism are respectively connected to the controller. When the open position sensor detects an open position signal, the controller controls the lifting mechanism to stop opening the door. When the close position sensor detects a close position signal, the controller controls the lifting mechanism to stop closing the door. By setting open and close position sensors to detect the open and close position signals of the door, the automatic operation of the lifting mechanism is achieved, thus improving the automation level of the door opening device.

[0038] Door opening component 2, which is matched with the pre-set functional part 3 on the door 1;

[0039] The lifting mechanism is used to drive the door opening component 2 to move vertically, thereby driving the corresponding compartment door 1 to move vertically through the cooperation of the door opening component 2 and the action part 3, realizing the opening and closing operation of the compartment door 1.

[0040] In the technical solution provided in this application embodiment, the door opening device is moved to the front of the warehouse door 1 that needs to be opened by the lifting machine.

[0041] In one specific embodiment, the hoist may be a stacker crane or other three-dimensional displacement platform.

[0042] Please continue reading. Figure 1 In some embodiments, the door opening component 2 is a door opening hook, and the actuating part 3 is a protrusion or recess that matches the door opening hook. By cooperating with the protrusion or recess in front of the door 1, the door 1 can be lifted. The lifting mechanism is used to realize the lifting and lowering closing actions of the door 1.

[0044] Please continue reading. Figures 1 to 4 In some embodiments, the lifting mechanism includes a driving component and a vertically arranged linear groove 4. A lifting rod 5 is slidably connected to the linear groove 4. The bottom end of the lifting rod 5 is connected to the door opening component 2. The driving component is used to drive the lifting rod 5 to move vertically on the linear groove 4, thereby driving the door opening component 2 to rise or fall and perform the action of opening and closing the compartment door 1.

[0045] Please continue reading. Figure 4 In some embodiments, the inner wall of the linear guide rail 4 is provided with a linear guide groove 6, and the outside of the lifting rod 5 is provided with a first guide wheel 7 that matches the linear guide groove 6. By providing a linear guide groove 6 inside the linear guide rail 4 and a first guide wheel 7 outside the lifting rod 5, the sliding engagement between the lifting rod 5 and the linear guide groove 6 is converted into a rolling engagement between the first guide wheel 7 and the linear guide groove 6 through the cooperation of the first guide wheel 7 and the linear guide groove 6. This reduces the friction between the lifting rod 5 and the linear guide rail 4, making the movement of the lifting rod 5 on the linear guide rail 4 smoother.

[0046] Please continue reading. Figure 2 , Figure 3 , Figure 5 In some embodiments, a guide sleeve 8 is fitted around the outside of the lifting rod 5, the lifting rod 5 is rotatably connected to the guide sleeve 8, the first guide wheel 7 is installed on the outside of the guide sleeve 8, and the driving component is connected to the guide sleeve 8 to drive the guide sleeve 8 to move vertically on the linear groove rail 4.

[0047] The lifting rod 5 is provided with a second guide wheel 9 that matches the straight guide groove 6. The bottom of the straight guide rail 4 is connected to an arc-shaped guide 10 that is coaxially arranged with the lifting rod 5. The arc-shaped guide 10 and the second guide wheel 9 cooperate with each other to make the lifting rod 5 rotate in the guide sleeve 8, which drives the door opening part 2 to rotate in the horizontal direction and cooperate with the action part 3 on the door 1.

[0048] This application provides a guide sleeve 8 that rotates around the lifting rod 5, a second guide wheel 9 that is mounted on the outside of the lifting rod 5, and an arc-shaped guide 10 that is connected to the bottom of the linear groove rail 4. This allows the lifting rod 5 to move upward and rotate simultaneously as the second guide wheel 9 rolls within the arc-shaped guide 10, thereby driving the door opening component 2 to rotate and cooperate with the action part 3 on the door 1 to lift the door 1.

[0049] In one specific embodiment, the guide sleeve 8 has a channel inside for the lifting rod 5 to pass through, and both ends of the guide sleeve 8 are provided with bearings for mounting the lifting rod 5. The lifting rod 5 is rotatably connected to the guide sleeve 8 through the bearings.

[0050] In one specific implementation, the linear channel rail 4 is a channel steel, and the guide sleeve 8 is a square steel pipe, which is slidably embedded inside the channel steel.

[0051] Please continue reading. Figure 4 In some embodiments, the inner wall of the arc-shaped guide 10 is provided with a curved guide groove 11 that matches the second guide wheel 9. The curved guide groove 11 is smoothly connected to the straight guide groove 6 and extends along the axial and circumferential directions of the arc-shaped guide 10 (the curved guide groove 11 is spirally arranged). The second guide wheel 9 moves spirally upward or downward in the curved guide groove 11, driving the lifting rod 5 to rotate upward or downward. By providing a curved guide groove 11 that smoothly connects to the straight guide groove 6 in the arc-shaped guide 10, the second guide wheel 9 can smoothly transition to the straight guide groove 6 when it moves spirally upward in the curved guide groove 11, thus improving the smoothness of opening and closing the door 1.

[0052] Please continue reading. Figure 2 In some embodiments, the driving component includes a drive motor 12 and a chain drive assembly installed inside the linear guide rail 4. The chain drive assembly is connected to the lifting rod 5. The drive motor 12 drives the chain drive assembly to run, causing the lifting rod 5 to move linearly in the vertical direction. The chain drive assembly can convert the rotational motion output by the drive motor 12 into linear motion, thereby causing the lifting rod 5 to move linearly in the vertical direction, realizing the opening and closing of the compartment door 1.

[0053] Please continue reading. Figure 5 In one specific embodiment, the chain drive assembly includes a drive gear rotatably mounted at the bottom end of the linear groove rail 4 and a transmission gear rotatably mounted at the top end of the linear groove rail 4. The drive gear and the transmission gear are connected by a transmission chain 15 for transmission. The transmission chain 15 is fixedly connected to the bottom surface of the guide sleeve 8. The output shaft of the drive motor 12 is connected to the drive gear. The drive motor 12 drives the drive gear to rotate, which in turn drives the transmission chain 15 to run, thereby driving the guide sleeve 8 to move along the linear groove rail 4.

[0054] In one specific embodiment, the drive motor 12 is driven by a high-precision stepper motor.

[0055] Please continue reading. Figure 1 , Figure 2In some embodiments, two linear groove rails 4 are provided, and the two linear groove rails 4 are arranged in parallel and connected by a crossbeam 16. The driving component is installed between the two linear groove rails 4 and is used to drive the two lifting rods 5 to move synchronously in the vertical direction on their respective linear groove rails 4. By setting two linear groove rails 4, it can be applied to a wider door 1. When the door 1 is wider, the actuating parts 3 can be set at the left and right ends of the door 1 respectively. The door 1 can be opened by the two opening parts 2 cooperating with the left and right actuating parts 3 respectively, thereby improving the stability of the opening device structure.

[0056] Please continue reading. Figure 2 In one specific embodiment, the drive gears in the left and right linear grooves 4 are connected by a synchronous shaft 17. The synchronous shaft 17 is connected to the drive motor 12 through gear transmission. The drive motor 12 drives the synchronous shaft 17 to rotate, thereby driving the drive gears on the left and right sides to rotate synchronously, thereby realizing the synchronous lifting of the lifting rods 5 and the door opening hook on the left and right sides, and performing the door opening action.

[0057] In some embodiments, the door opening device further includes an open position sensor and a close position sensor. The open position sensor, the close position sensor, and the lifting mechanism are respectively connected to the controller. When the open position sensor detects an open position signal, the controller controls the lifting mechanism to stop opening the door. When the close position sensor detects a close position signal, the controller controls the lifting mechanism to stop closing the door. By setting the open position sensor and the close position sensor to detect the open and close position signals of the door 1, the automatic operation of the lifting mechanism is realized, thereby improving the automation level of the door opening device.

[0058] In one specific implementation, the bottom outer side of the linear groove rail 4 is provided with a mounting bracket 18 for fixing the door opening device to the stacker crane's own hoist.

[0059] The working process of the door opening device in this embodiment is as follows:

[0060] The door opening device first executes an initialization command, controlling the drive motor 12 to drive the lifting rod 5 to descend to the initial position (e.g., Figure 6 As shown, at this time, the second guide wheel 9 is located at the bottom end of the curved guide groove 11, and the corresponding door opening hook rotates to the direction facing outwards from the door 1.

[0061] According to the door opening command, the stacker crane uses its built-in hoist to move the door opening device to the target warehouse location (the target warehouse location can be automatically identified by the warehouse location identification module built into the stacker crane).

[0062] The drive motor 12 drives the drive gear to rotate forward, which in turn drives the guide sleeve 8 to move vertically upward through the transmission chain 15. During the upward movement of the lifting rod 5, the second guide wheel 9 spirals upward along the curved guide groove 11, forcing the lifting rod 5 to rotate forward. This causes the end of the door hook to rotate into the rectangular blind hole on the door 1. Figure 7 As shown; when the door opening hook rotates to the correct position, the second guide wheel 9 moves to the position where the curved guide groove 11 connects with the straight guide groove 6. At this time, both the first guide wheel 7 and the second guide wheel 9 are located in the straight guide groove 6. The drive motor 12 continues to drive the active gear to rotate forward, and through the transmission chain 15, it drives the guide sleeve 8 to continue to move vertically upward. During the upward movement, the lifting rod 5 drives the door opening hook to move upward, thereby lifting the target compartment door 1 to open up and down. When the door opening position sensor detects the door opening position signal, the drive motor 12 stops running, and the door opening action of the compartment door 1 is completed.

[0063] When the door 1 is open, the stacker crane can perform picking / placing operations at the target location. After the picking / placing task is completed, the drive motor 12 drives the drive gear to reverse, which drives the guide sleeve 8 to move vertically downward through the transmission chain 15. During the downward movement, the lifting rod 5 drives the door hook to move downward. Under its own weight, the door 1 also moves downward with the door hook to achieve the closing operation. When the door 1 is completely closed, the second guide wheel 9 just moves to the position where the curved guide groove 11 and the straight guide groove 6 meet. The drive motor 12 continues to drive the drive gear to reverse, which drives the guide sleeve 8 to continue to move vertically downward through the transmission chain 15. During the downward movement of the lifting rod 5, the second guide wheel 9 moves downward spirally along the curved guide groove 11, forcing the lifting rod 5 to reverse, so that the end of the door hook rotates to the direction facing outward of the door 1 (i.e., the initial position). At this time, the door hook is completely disengaged from the rectangular blind hole on the door 1, and the closing operation of the door 1 is completed.

[0064] The door opening device in this application is used in the maintenance warehouse, and the warehouse door 1 of each floor can be opened by lifting it upwards.
